Graceful shutdown to clean up canceled deployment

Is your feature request related to a problem? Please describe.

I encountered an issue when using Zarf to deploy a failing application. During the deployment, I used Ctrl-C to interrupt the process, but this did not allow Zarf to clean up the state it put in the cluster. As a result, I am forced to wait for the deployment to fail multiple times before Zarf can properly clean up the failed deployment, which can take a significant amount of time (up to 15 minutes per timeout).

Describe the solution you'd like

I propose implementing a graceful shutdown signal when using Ctrl-C during deployment. This will allow Zarf to clean up the cluster state if the deployment is interrupted. Additionally, if Ctrl-C is used during the graceful shutdown, it should trigger a hard stop like it currently does.

Describe alternatives you've considered

An alternative solution would be to provide a separate command to manually trigger a cleanup of a failed deployment in the cluster. This would allow users to clean up the state without waiting for multiple deployment timeouts. The current zarf package delete command fails to clean up a failed deploy due to some secret not existing that it expects.

Additional context

This improvement would save users time and frustration when dealing with failed deployments in Zarf. By implementing a graceful shutdown signal upon using Ctrl-C, users can have more control over their deployment process and avoid waiting for extended periods due to multiple timeouts.
